Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film-integrated camera, such as a disposable camera, in which a film is loaded in the camera in advance by a manufacturer.

[Background of the Invention]

In general, this type of film-integrated camera uses a film cartridge loaded with 110 or 126 type film. This is in order to reduce the size of the camera body. However, in such a type of film, since the area of one frame is small, a full-size screen of a 35 mm film (24
When comparing an image photographed at (mm × 36 mm) with a printed image after enlargement, it was inevitable that the sharpness and the graininess were inferior. For this reason, 35mm film (roll film J135 [JISK7519] is converted into a special patrone [JISK7528]
The use of a film-integrated camera that can be used in a light-tight state has been desired.

However, even with such a film-integrated camera, the appearance of the camera itself is not much different from that of a normal interchangeable film camera, since the minimum mechanism necessary for taking a picture must be installed, As long as a patrone with film was used, there was a limit to miniaturization. That is, in order to use a patrone with a 35 mm film for this kind of film-integrated camera, the patrone is loaded into a rewinding room (film storing room) in the camera body, and a light-tight empty space in which the film can be stored. A film container (or an empty patrone) may be loaded into the film winding chamber, and the film may be wound into an empty film container in the film winding chamber, and when the camera is finally broken, the film is taken. It is necessary to take out the whole container so that it can be developed.

However, as long as such a film container is used, a winding mechanism for the film container loaded in the film winding chamber is absolutely necessary, and this winding mechanism requires a large installation space, and the space is equivalent to the camera space. This caused the vertical dimension of the main unit to increase.

[Object of the invention]

SUMMARY OF THE INVENTION In view of the above, the present invention provides a film-integrated camera in which a shaft of a winding knob and a spool of a film container can be easily connected to each other, and the installation space for a winding mechanism for a spool of a film container is omitted to reduce the size. It is intended to be.

[Structure of the Invention] In order to achieve the above object, in the present invention, an unexposed film is loaded in a film storage chamber in advance, and an externally operable unit is turned for each frame by rotating a winding knob for each frame. A film-integrated camera that winds up the film in a film winding chamber and takes out the film that has been photographed after photographing is completed, wherein the film winding chamber has a cylindrical end with a shaft portion of the winding knob. Incorporating a film container having a spool with a projection formed on the inner surface inside, and forming a number of protrusions extending in the axial direction around the shaft of the hoisting knob, so that the spool and the shaft are joined. In the state
The projection is located between adjacent projections of a number of projections formed on the shaft of the hoisting knob.

〔Example〕

Next, a film-integrated camera according to the present invention will be described with reference to the accompanying drawings.

Reference numeral 11 denotes a camera body. The camera body 11 is obtained by independently molding and combining a front frame 11a and a back frame 11b, and has an exposure chamber a therein and a film sandwiching the exposure chamber a. A rewinding room b and a film winding-up room c, which are storage rooms, are provided. Thus, before the camera body 11 is integrated, the first film container 12 containing the 35 mm film is loaded into the rewinding room b, and the empty second film container 13 capable of winding the film is put into the film winding room c. Incorporate in In this case, the drawing end of the film 15 drawn from the first film container 12 is connected to the spool 14 in the second film container 13 and wound in advance. Also, the spool 14 of the second film container 13
The shaft 16a of the hoist knob 16 is directly connected to
When uniting 1, the head 16 b of the hoisting knob 16 is exposed outside the camera body 11 through the through hole 19 provided on the dividing line on the upper surface. The shaft portion 16a of the hoisting knob 16 has a plurality of ribs (convex portions) 17 provided on the outer peripheral surface of the lower end portion along the axial direction, and protrusions 14a, 14b provided at positions facing the inner peripheral surface of the spool 14.
As shown in FIG. 4, they are engaged only by being inserted, and after the engagement, they do not slip in the rotational direction.

The hoisting knob 16 is for rotating the spool 14 only in the hoisting direction to transfer the film from the first film container 12 to the second film container 13, and the shaft portion 16a of the shaft portion 16a prevents reverse winding in advance. (A ratchet claw is not shown) 18 is fixed. The ratchet gear 18 is also free in the axial direction, but does not slide in the rotational direction.

The first and second film containers 12 and 13 each have a light-tight structure, and a film-containing patrone and an empty patrone having the same shape may be used as they are. In this case, the film in the film-containing patrone is drawn out to a maximum in a dark room or a light-tight device, and the entire length is wound in an empty patrone in an unexposed state, and the patrone side wound by this is the first film. Used as container 12,
The empty patrone side may be used as the second film container 13. That is, the film-containing patrone used as the first film container 12 has a core (spool).
In this case, the inner end (end) of the film is not fixed, so that the whole wound film can be transferred into the empty cartridge.

Although not explicitly shown in the drawings, the first film container 12 and the second film container 13 may of course be integrally formed as a cartridge.

The winding knob 16 has a second film container in the camera body 11.
Before assembling 13, the shaft portion 16a was directly connected to the spool 14 of the second film container 13.On the contrary, the second film container 13 and the ratchet gear 18 were connected inside the camera body 11 as predetermined. After incorporating the camera body 11 into the
The shaft 16a may be inserted into the spool of the second film container 13 from the outside through the through-hole 19 to directly connect the spool.

That is, in manufacturing the camera, the winding knob 16 is connected to the spool of the film container, and then the container is incorporated into the camera main body. There are two cases where the camera is connected to the spool of the container. However, since the form after the direct connection is the same, the method of manufacturing the camera may be selected in consideration of the flow of the entire manufacturing process.

It is necessary to shield the camera body 11 from the winding knob 16 exposed to the outside through the through hole 19 on the upper surface thereof.
There are various modes of the light shielding means, and one example is shown in FIGS. 1, 3 and 4. FIG. In the case of FIG. 1, the annular ribs 21 and 22 are raised concentrically around the side of the through hole 19 provided on the upper surface of the camera body 11 opposite to the hoisting knob, while the annular ribs 21 are inserted to make a tape-like shape. Annular rib 21 that engages with
And a concave groove 23 formed by a wall portion surrounding the shaft and the shaft portion 16a of the hoisting knob 16, and a concave groove 24 into which the annular rib 22 enters and engages in an eclectic manner. , 22 are provided on the lower surface, which is the surface facing the side, to form a light maze, thereby forming a light shielding means.

In the case of FIG. 3, an elastic light-shielding plate 26 having a through-hole 25 which can be in close contact with the outer peripheral surface of the shaft portion 16a of the winding knob 16 is provided on the upper surface of the annular rib 21 raised around the through hole 19 of the camera body 11. This is an example of sticking as shown in FIG. A and allowing light to be shielded as shown in FIG.

In the case of FIG. 4, a light-shielding member (a light-shielding cloth area or the like) is provided so that the inner peripheral surface of the annular rib 21 raised around the through hole 19 of the camera body can be in close contact with the outer peripheral surface of the shaft portion 16a of the winding knob 16. This is an example in which a light-shielding sponge (27) is attached to allow light to be shielded.

Needless to say, a mechanism necessary for photographing is incorporated in the camera body 11 in advance. Hereinafter, these mechanisms will be described with reference to the diagram schematically shown in FIG.
In the figure, reference numeral 28 denotes a sprocket meshed with the perforation P of the film 15 which is shifted by rotating the winding knob 16 in the winding direction, and 29 denotes a sprocket 28.
Reference numeral 30 denotes a shutter charge plate fixed to a cam plate. A pin 29a is provided at a symmetrical position on the upper surface of the cam plate 29, and the pin 29a extends the shutter charge plate 30 during the half rotation of the cam plate 29 (corresponding to the rotation amount for winding the film 15 over one screen). The shutter charge plate 30 is moved rightward in the figure against the tension spring 31 by engaging with the portion 30a. Due to this movement, the notch 30b provided at the end of the shutter charge plate 30 is engaged with the protrusion 32 'of the relays plate 32. This locking is performed before the half rotation of the cam plate 29 is completed, and after this point, the pins 29a are disengaged from the projecting portions 30a of the shutter charge plate 30. Therefore,
The shutter charge plate 30 is applied with a force in the direction of returning by the action of the tension spring 31. However, the state (shutter charge state) is maintained unless the release plate 32 is pressed to release the above-mentioned locking. At this time, the cam plate 29
A step (not shown) provided at a symmetrical position on the outer periphery of the lock is engaged with a stopper (not shown) so that the hoisting knob 16 is not further rotated. When the release plate 32 is pressed and the shutter charge plate 30 returns to the initial position, the stopper comes off the step in the process.

The shutter charge plate 30 is provided with a shutter hitting piece 30c which is pivotally supported so as to be rotatable only in a clockwise direction. Therefore, when the shutter charge plate 30 moves rightward, the shutter Hitting piece 30c is shooting lens 33
When a pin on the head of the shutter blade 34 that blocks the optical path of the shutter blade is hit, the shutter blade 34 turns over and rides over the pin. Therefore, when the release plate 32 is pressed and the shutter charge plate 30 returns from the charge position with the action of the tension spring 31, the shutter hitting piece 30c hits the pin on the head of the shutter blade 34 in the process. As a result, the shutter blade 34 rotates about the support shaft 35 to open the optical path of the photographing lens 33, and then quickly returns to the original state by the action of the opening spring 36.

Reference numeral 37 denotes a counter window for displaying the number of film shots (or the remaining number). The counter window 37 has the sprocket
Each time a gear (not shown) rotating in connection with 28 rotates half a turn, a scale of an index plate (not shown) that rotates by one scale is exposed. 38 is a simple direct view finder.

In the above embodiment, when the photographing of a predetermined number of screens is completed, all the films are stored in the light-tight second film container 13, so that the camera body 11 is broken by an appropriate method and the film container is taken out. Can be. You can do this in a light room.

〔The invention's effect〕

As described above, according to the present invention, the hoisting knob and the spool of the film container can be connected without much concern for the rotational direction positions of the both, so that the assembling is simple and the space required for installing the hoisting mechanism is small. Can be omitted to provide a film-integrated camera in which the vertical direction is reduced.
